Original application filed August 12, 1810, Serial No. 576,822.

Serial No. 619,001-

T all whom 1'2. may concern Be it known that I, Ania-mus N. HADLEY, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Traction-Wheel. of which the following is a specification, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon.

This invention relates to driving wheels for portable agricultural engines of the type that is adapted for use in fields for drawing plows.-cultivators. or other agricultural implements. or to operate on highways or other roads. not only in self propulsion, but for hauling vehicles or portable machinery from place to place. the invention having reference particularly to driving wheels having ad justable and movable adhesion-incrensers.

An engine having the improved driving wheels is illustrated in my pending application for Letters Patent, Serial No. 576.822, tiled August 12, 1910, from which the present application for Letters Patent is divided out.

' The primary object of the present inven tion is to provide an improved driving wheel especiall adapted for use on relatively soft ground and adapted to ati'ord the maximum adhesive force without being retarded on account of sticky soil.

Another object is to provide improved adhesion-increascrs. and adjustable operating apparatus therefor that will be adapted to be reliable under varying conditions of operation.

Vv'ith the above-mentioned and minor objects in view. the invention consists in an improved driving wheel provided with improved adhesion-incrensers that are projectable through the rim of the wheel, and improved mechanism for varying the extent of the downward projection and also for varying the extent of projection of the adhesionincreasers forwardly or rearwardly rela-, tively to the periphery of the wheel; and the invention consists further in the parts, and c mbinations and arrangements of parts, as hereinafter particularly described and claimed.

Referring to the drawings, Figure 1 is a top plan of a portable engine illustrating the peculiar purposes of the improved driving wheels; Fig. 2, a side elevation of one of the driving-wheels; Fig. 3., a vertical section on the line A A in 1; F l a fragmentary section on the plane of the line B B in Fig. 3; Fig. 5, a fragmentary section on the plane of the line C C in Fig. 3; Fig. 6, a fragmentary section on the plane of the line D l) in Fig. 1; Fig. Lie side elevation of a sectional collar or hub employed in connection with the adhesion increesers; Fig. 8, a perspective view of one of the lugs for holding the parts of the collar together; Fig. 9, an elevation of one part of the sectional collar; and Fig. 10, a fragmentary sectional elevation on the plane of the line E E in Fig. 6.

Similar reference characters in the different fignresiof the drawings indicate corresponding elements or features of construction herein referred to.

In order to clearly illustrate the adaptability of the improved driving wheels for the purposes intended and to clearly show the relation of the wheels to the engine frame, the more essential features of the engine are herein briefly illustrated and described. said engine comprising a frame suitably composed of longitudinal beams, l, 1, two end members. 2. 2. two transverse beams. 3, 3'. and similar transverse beams, l, l. secured to the longitudinal beams, and other transverse members 5, 6, T. secured also to the longitudinal beams. The lateral portions of the frame are each provided with a downwardly extending pedestal comprising each a pair of members 8 and 8'. having a plate 9 secured thereto, the plate 9 having a reinforcing plate 10 thereon, another plate 11 being secured to the pedestal members and having a relatively thick reinforcing plate 1'2 secured thereto. The

plates 9, 10. 11, -12. are suitably apertured to receive an axle 13 or 13', there being two axles of identical construction employ- Each axle has a collar 14 thereon. preferably integral therewith. in the periphery oiwhich is a suitable number of sockets 15. The sockets are adapted to receive an operatin g bar for turning the axle adjustably and for holding it when adjusted until secured tightly in the desired position, one end portion of each aide being mounted in a pedestal so as to be adjustable rotatably therein, and the collar 14: is in contact with the plate 10, there preferably being a washer 16 on the axle in contact with the plate l2. ldlach anle has a threaded end portion 17 on which is a nut 18 that is seated against the washer for securing the aide tightly in the pedestal when adjusted. Each axle has an oil-set portion 19 between its ends,-- formed between the collar lland one end portion of the axle, so that the axle is substantially the same as a crank-shalt.

A. driving wheel is provided tor each aide and each wheel comprises a hub which prcterably consists oi two sections 20 and 2D, the hub being mounted rotatirely on the between the collar 1t and the oil-set portion or crnnlr and a web portion comprising preferably two parts 21 and 21., is secured to i the hub and has a rim thereon preferably composed of two parts i292 and 22' suitably secured together. The rim has an inwardly enteriding tlange 23 on its outer edge. A huh is mounted rotativelyon the outer end oil sale and has a dies: 25 thereon. which is connected detachably 928 the dish pret'erabl being detachable from the hub. Each w'ieel as will seen is hollow and adapted to be used on soft ground the lace of the rim being eulhciently oroad to sustain the weight oi the machine, the webs or disks excluding the soil from the interiorot the wheels. .Each driving- I wheel has a suitable number of apertures or till till

slots 2% in its rim in each of which a blade 2? is arranged morably, each blade preterably having a suitable number of strengthening rib 28 thereon: Each blade has suitable shanlr 29 on opposite sides of; which are trunnions 30, 30'.

in order to control the blades which constitute.adhesion-increasers, a suitable collar or hub is provided which comprise two ill. plane at right angles to the aide, each being composed of two pieces, as 3t in. t, 9", apertures 39 therein to receive the trunnions and provided-with recesses in which are so clrets to receive which are prorided that projections and 3t to be insert ed in the sockets :tor the two pieces at each to gether the pieces halving also bolt holes 3? therein to receive bolts lit: whereby two the collar are secured together, the collar rotatire on the oldet portion it an provided with opposing or hi it?) I n n a l v v and a uapted to be engaged by the st anhs the bio letter the collar, the

which the trunnione *tore the blades may and ti that are separable on i are arranged in a circle about the axis of the oil-set portion oi the axle concentrically thereto. 'll'wo sectional collars l-U and d0 are placed on the oil-set portion at the oppositesides of the operating collar to prevent the latter from moving sidewise, the parts of the collars 4-0 and &0 being connected together by bolts ll.

llt will be seen from the foregoing that while the wheel rotates on one axis it carries the blades around another axis, and therebe "forced beyond the rim of the wheel into the ground while the blades in the opposite side of the wheel are retracted relatively to the wheel. llt will be clear also that it the oil-set portion ll) be adjlusted so as to b below the axis of the main portions oil the axle, the blades project downwardly, but will project upwardly it the oil-set portion be adjusted so as to be above the said axis and consequently with the latter arrangement the blades are retracted or disappear from the portions of the rim that are in contact with the roadway lt should be understood also that by readjustment oil the axle so that the oil-set portion is brought either forward or rearward oi the rotative axis or the wheel the extent of movement of the blades into the ground may be controlled to suit conditions and be caused to operate at or? inclination to the ground.

l he inner side of each drivingovheel has a ring 42 thereon that has internal gear'teeth 43, so as to constitute a relatively large gearwheel which is provided with lugs ll whereby it is secured to the driving-wheel. 'llwo driving-shafts t5 and to are mounted rotatirel r in suitable journal bones do &6, secured on the top of the lateral portion of the frame, each shaft having a pinion l'l secured. thereto that meshes with the gear s-t eeth The shafts t5 and l5 are in alincrnent and their inner ends'are connected with suitable dih'erential caring mounted in a casing 48., the gearing eing of any preferred or well lrnown type and provided with a sprocket-wheel d9.

A suitable motor is mounted upon the :lrarae and is provided with a bevel gear wheel-5i il counter-shalt 52 is mounted on the rotatirely and has a sprocketwheel secured thereto to which is connected a sprocket-chain 5d that is connected to sprocket-wheel 49. Two bevel gearwheels t lt and 55 are connected together and mounted slidingly on a counterehaift and suitably splined thereto so that either one may be moved into engagement with the near-wheel til. A lever 5t 1 mounted on the Home and adapted to shift and control the wheels and 55} an operating rod 5'? be connected to the lever an. also to a relerer 58 mounted on llll mes es A steering-head 59 is mounted rotatively in the member 5 of the frame, so as to turn on a vertical axis, and it has a stein 60 thereon that is arranged at one side of its own rotative axis, the stem constituting a wheel frame on which steering wheels (31 and 61 are mounted. The steering head has a gear wheel 62 thereon and adjacent thereto is a frame 63 adjustably-inounted upon the main frame and supporting a worm (i l which is held in contact with the gear-wbeel 62 by a suitable latch (55. Said steering apparatus being fully described in said pending application requires no further description but will be understood as being adapted to enable the operator to guide the engine, or permit the worm 6-1- to be disconnected from the gear-wheel 62 so that the wheels (31 and 61' may trail and support-oneend of the frame while steering may be accomplished by means of the driving wheels. The lateral portions of the frame are provided with suitable draft devices 66, 66, and similar devices 67, 67, so that gangs of plows or other implements may be hitched to the engine. which. as will be seen, may be run either forward or backward.

In practical use, the blades 27 being.

nearly as broad as the face of the wheelrim, sink into the' soft ground during rotation of the wheel and prevent the wheel from slipping, the driving wheels being actuated as will be seen by powerful gearing. As the driving-wheels rotate and carry the blades out of the ground the latter are drawn inward so that the soil adhering to them is scraped ed by the periphery'of the wheel. According to conditions oi the round, the axlesmay'be readjusted so as to ring the ofi' set portions eithenhnnvardly or reurwardly', and especiallrn'iay this be desired when operating the engine first in one directionand then in the'opposite direction, and it willbe clear that the adjust ments maybe such as to vary'the extcnt to which the blades may enter the ground;
